Definitions

  • the subject invention relates to a collapsible steering column assembly including an energy absorbing mechanism.
  • Collapsible steering column assemblies are known in the art for including in vehicles to reduce the likelihood of injury to occupants of the vehicles during collisions.
  • the steering column assemblies include a support for attachment to the vehicle.
  • a steering column is movably supported by the support.
  • An energy absorbing mechanism interconnects the steering column and the support for absorbing energy in response to the steering column moving relative to the support, i.e., when a force is exerted on the steering column such as during the collision.
  • Common energy absorbing mechanisms include a metal strap that is wrapped about an anvil.
  • the metal strap is generally fixed to the steering column and the anvil is fixed to the support.
  • the metal strap resists the movement and bends about the anvil, thus absorbing the energy and allowing the steering column to move in relation to the support.
  • One of the problems with the energy absorbing mechanisms is that the metal straps are selected to deform when a force exerted on the steering column exceeds a predetermined threshold. As a result, the energy absorbing mechanism is exhausted after absorbing the energy when the force exceeds the threshold and cannot absorb additional energy thereafter. For example, during the collision, the force of the collision itself may exceed the predetermined threshold.
  • the energy absorbing mechanism cannot absorb any more energy. Furthermore, collisions generate forces of various magnitude on the steering column, depending on the speed of the vehicles involved, among other variables.
  • the metal straps, chosen to deform at the predetermined threshold are not suitable to absorb energy at forces below or substantially above the predetermined threshold. In other words, the metal straps, because of the predetermined threshold, are based on predetermined collision conditions and cannot adjust to actual collision conditions. In addition, the metal straps, once deformed, lose structural integrity and must be replaced.
  • the subject invention provides a collapsible steering column assembly including a support for attachment to a vehicle.
  • a steering column is movably supported by the support.
  • An energy absorbing mechanism interconnects the steering column and the support for absorbing energy in response to the steering column moving relative to the support during a collision.
  • the energy absorbing mechanism includes an elongated element movable along a longitudinal axis in response to the movement of the steering column.
  • the energy absorbing mechanism further includes a brake for variably resisting the movement of the elongated element.
  • the elongated element in combination with the brake, is capable of adjustment to absorb energy at forces of various magnitude such that a universal energy absorbing device may be installed on each type of vehicle and adjusted based on individual parameters of the vehicle.
  • FIG. 1 is a schematic side view of a collapsible steering column assembly including an energy absorbing mechanism prior to collapse of the assembly;

  • the assembly 10 is included in a vehicle for collapsing to minimize injury to occupants of the vehicle during a collision.

  • the support 12 includes a frame 16 for receiving the steering column 14 .
  • the frame 16 defines a shape corresponding to a shape of the steering column 14 .
  • the steering column 14 preferably defines a box-shaped cross-section in a plane perpendicular to a longitudinal axis L of the steering column 14 .
  • the steering column 14 is movable through the frame 16 along the longitudinal axis L.
  • the shape of the frame 16 corresponds to the shape of the cross-section for guiding the steering column 14 as the steering column 14 moves through the frame 16 .
  • the steering column 14 defines the cross-section in any variety of shapes including circular, triangular, etc.
  • At least one shear capsule (not shown) is disposed between the vehicle and the steering column 14 for immobilizing the steering column 14 during normal driving conditions.
  • forces between the steering column 14 and the vehicle cause the shear capsule to rupture, thus releasing the steering column 14 from the immobilized position.
  • An energy absorbing mechanism 18 interconnects the steering column 14 and the support 12 . It is to be appreciated that the energy absorbing mechanism 18 may interconnect the steering column 14 and any part of the vehicle adjacent to and fixed with respect to the steering column 14 . The energy absorbing mechanism 18 absorbs energy in response to the steering column 14 moving relative to the support 12 during a collision.
  • the energy absorbing mechanism 18 includes a elongated element 20 that is movable along a longitudinal axis L in response to the movement of the steering column 14 .
  • the energy absorbing mechanism 18 further includes a brake 30 for variably resisting the movement of the elongated element 20 and absorbing the energy during the collision.
  • variably resisting it is meant that the brake 30 absorbs energy at forces of various magnitude.
  • the elongated element 20 is sufficiently flexible to provide insubstantial resistance to bending and, in combination with the brake 30 , is capable of adjustment to absorb energy at forces of various magnitude such that a universal energy absorbing device may be installed on each type of vehicle and adjusted based on individual parameters of the vehicle.

  • the elongated element 20 is cable-like and has a circular cross-sectional shape.
  • the flexible feature of the elongated element 20 means that the elongated element 20 offers negligible or no resistance to bending and merely transmits forces in tension, i.e., there is no energy absorption due to bending forces.
  • the energy absorbing mechanism 18 includes a roller 22 rotatable about an axis A.
  • the axis A is transverse to the longitudinal axis L of the steering column 14 .
  • the elongated element 20 has a first end 24 wound about the roller 22 for unwinding and rotating the roller 22 about the axis A in response to the movement of the steering column 14 relative to the support 12 .
